It’s a man’s world, but maybe not for much longer. Scientists say males are on the road to extinction as their genes slowly fade away. And with the world heading for a fully-fledged sperm crisis, Russia could be affected worse than most.

­In a horrifying mutation, sperm with two heads, three tails or an inability to swim are becoming almost the norm amongst modern men.

“What used to be perceived as infertility is now very different. Twenty years ago, 200 million viable sperm per milliliter was considered normal. Today, 15 million is average,” Margarita Anshina, director of the Center for Reproduction and Genetics, told RT.

But proper sperm studies are not easy, and have never been conducted in Russia – until now. Professor Galimov was among the first, only to find more than half of his fellow countrymen’s sperm did not meet World Health Organization standards.
